LTC2051HVCMS10#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LTC2051HVCMS10#TRPBF is a dual zero-drift operational amplifier in a 10-lead MSOP package. It supports single supply voltages from 2.7V to ±5.5V and operates within an extended temperature range of –40°C to 125°C. Key electrical specifications include a maximum input offset voltage of 3μV, a typical gain-bandwidth product of 3MHz, and a supply current of 0.75mA per amplifier at 3V. The device features rail-to-rail output swing, high common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) exceeding 130dB, and low DC-to-10Hz noise.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Zero-drift architecture utilizing autozeroing circuitry to achieve near-zero DC offset and drift across temperature and supply variations.
• Extended common-mode input range extending from the negative supply up to typically 1V below the positive supply.
• Rail-to-rail output stage capable of driving loads as low as 2kΩ to both supply rails.
• Integrated shutdown pin for active-low control, reducing supply current significantly when disabled.

Instrumentation, Op Amps, Buffer Amps Applications

• Thermocouple amplifiers
• Electronic scales
• Medical instrumentation
• Strain gauge amplifiers
• High resolution data acquisition

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging with lead-free compliance. Confirm the HV designation indicates support for higher total supply voltages up to 12V compared to standard variants. Ensure the MS10 package matches the required footprint and pinout for the target PCB layout.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring ultra-low offset voltage and drift without external trimming. The HV variant is suitable for systems operating with higher supply rails or wider common-mode ranges. Consider the 10-lead MSOP package if additional pins such as shutdown control are needed compared to the 8-lead version.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LTC2051/LTC2052 family of precision zero-drift operational amplifiers. The HVC designation denotes high-voltage capability supporting ±5V supplies, while the MS10 suffix specifies the 10-lead plastic MSOP package. The #TRPBF suffix indicates it is supplied in tape and reel format with lead-free construction.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

LTC2051HVCMS8#TRPBF offers identical electrical performance in an 8-lead MSOP package without the shutdown pin. LTC2051HVIMS10#TRPBF provides the same functionality but with industrial temperature range guarantees (-40°C to 85°C) instead of the extended range.
